Re: Piston or Wedge QCTP.

Thanks Pete, very clever and can be done without a DRO Harold! Chuckle! Truthfully, almost all functions can. They just make it easier! :wink: I realize I've harped on this subject a little---maybe even a little too much, but I used to do extremely challenging work, and all without the use of DRO's...

Re: Considering a DRO

I agree totally, especially when one already possess the basics of machine operations. Doesn't mean it can't be done without the DRO, but owning the device certainly can't hurt. Just don't rely on them to create ability. They don't do that. That comes from experience. The one place one must be caref...

Because there's room to share our experiences on this board. So long as folks stay polite, and avoid politics and religion, their comments are welcome.

Re: Considering a DRO

I get it. The harsh reality is that not everyone has need (nor desire) to master machining. For some folks, their machine tools are nothing more than a means to an end---they want to build a widget, and machine tools are required. They have no aspirations of becoming a machinist, and have little int...

Re: Fire Danger

How does a titanium fire respond to water? I know, from personal experience, that the situation described above would border on the impossible to extinguish should the material be magnesium.

If you haven't witnessed water being introduced to a magnesium fire, you haven't lived!

Re: Considering a DRO

A machinery dealer once told me if you don't have a DRO you are living in the dark ages, guess I am still living in the dark ages, do everything manually. Heh! Dealers of smart phones would likely parrot that comment. Anyone watch the news about a week ago, to see an individual walk off the platfor...

Re: metric drill swap

<snip> Sometime is a good idea to double drill to avoid going oversize. A drill shaving a few thousands is not going to improve location or straightness but it will improve roundness and size. Yep! And this bit of information is something that all machinist types should understand. Double drilling ...

Re: Considering a DRO

I question the need. I was trained on manual machines and have never used a DRO. Seems to me like a lot of money to spend with not such a great return, but then I have the utmost confidence in my ability. That didn't come fast, or easy. H but then you also grew up in a generation where you did math...

Re: USATC S-160 Consolidation

Thanks, Dick. I trust when you say you have a propane foundry that you mean you have a propane furnace? A foundry is where castings are poured, while a furnace is what melts the metal. I've seen this several times, so the terminology is quite regularly misused. I have a burnout oven, but it needs a ...

Re: USATC S-160 Consolidation

Nice work, Dick. Fairly large for investment, so I can only assume that you have a powered centrifuge, or are you vacuum casting? How are you melting the metal? So many questions! For good reason, though. I hope to get my investment casting equipment operational soon. I have much to learn! H
